BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘GED18ADU7P’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum X morifolium ‘Aduro Violet’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a single plant from within a population of plants of ‘Aduro Violet’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2015.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2016. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘GED18ADU7P’. These characteristics in combination distinguish ‘GED18ADU7P’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright, outwardly spreading and uniformly rounded plant         habit; moderately vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Dark green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Long flowering period.     -   6. Decorative-type inflorescences with ray florets that are         initially red purple in color becoming light purple and lighter         red in color with subsequent development giving the         inflorescences a bi-colored appearance.

Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘Aduro Violet’. Plants of the new Chrysanthemum differ primarily from plants of ‘Aduro Violet’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are more uniform than plants         of ‘Aduro Violet’.     -   2. Ray florets of plants of the new Chrysanthemum are initially         red purple in color becoming light purple and lighter red in         color with subsequent development giving the inflorescences a         bi-colored appearance whereas ray florets of plants of ‘Aduro         Violet’ are pink and violet in color.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘Aduro Bronze’, disclosed in U.S. Plant patent application Ser. No. 15/732,915. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Aduro Bronze’ in ray floret color as ray florets of plants of the new Chrysanthemum are initially red purple in color becoming light purple to lighter red in color with subsequent development giving the inflorescences a bi-colored appearance whereas ray florets of plants of ‘Aduro Bronze’ are initially red purple in color becoming greyed orange in color with subsequent development giving the inflorescences a bi-colored appearance.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘G19ADU09MA’, disclosed in U.S. Plant patent application Ser. No. 15/732,899. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘G19ADU09MA’ in ray floret color as ray florets of plants of the new Chrysanthemum are initially red purple in color becoming light purple to lighter red in color with subsequent development giving the inflorescences a bi-colored appearance whereas ray florets of plants of ‘G19ADU09MA’ are dark red purple in color.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum X morifolium ‘Vigorelli Violet’, disclosed in U.S. Plant Pat. No. 23,965. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Vigorelli Violet’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are not as vigorous as plants         of ‘Vigorelli Violet’.     -   2. Plants of the new Chrysanthemum flower two weeks earlier than         plants of ‘Vigorelli Violet’.     -   3. Ray florets of plants of the new Chrysanthemum are initially         red purple in color becoming light purple and lighter red in         color with subsequent development giving the inflorescences a         bi-colored appearance whereas ray florets of plants of         ‘Vigorelli Violet’ are initially dark red purple in color         becoming lighter red purple in color with subsequent development         giving the inflorescences a bi-colored appearance.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of a typical flowering plant of ‘GED18ADU7P’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007, Fifth Edition, except where general terms of ordinary dictionary significance are used.
